ēchos althéa is the reverberation of stillness — a meeting point between sound, spirit, and self. It embodies the harmony that exists when we slow down enough to listen — to our bodies, our breath, and the subtle frequencies that guide us back to balance.
Where sound
becomes healing.

The Journey Within
Inspired by Orphēus, the legendary musician and healer whose song could soften even stone, Orpheus invites you into a one-on-one journey of resonance and renewal. Through crystal frequencies, harmonic sound, and intuitive energy work, these private sessions open space for deep release and re-tuning of the nervous system.
Each tone becomes a bridge — between body and spirit, between what has been held and what is ready to flow.
A sacred return to your own frequency.

Together in Vibration
Rooted in the ancient Greek word sýn — meaning together, in union — this experience celebrates the beauty of shared resonance. In a softly lit soundscape, crystal tones and layered frequencies invite the group into stillness, synchronicity, and connection.
As vibrations merge, boundaries soften. Individual rhythms harmonize into one collective field. Sýn is both a ceremony and a remembering — that we heal, rise, and expand together.
One sound. Many hearts.

Sýn Sound Session: Nervous Systen Reset
This immersive sound bath combines crystal singing bowls, gentle instrumentation, and guided breath and body awareness to support your nervous system in shifting out of stress and into regulation.
As the body settles into stillness, the mind naturally softens. Many participants experience a sense of spaciousness, emotional release, or deep restorative calm — similar to the moments just before sleep, while remaining aware.
No experience with meditation is needed. Your only role is to lie down, get comfortable, and receive.
